technicians, and automation enthusiasts aiming to harness the full potential of Delta

Human Machine Interfaces (HMIs). Whether you’re new to industrial automation or looking

to deepen your understanding of Delta’s HMI software capabilities, exploring real-world

examples can make the learning curve smoother and more enjoyable. In this article, we’ll

delve into a variety of Delta HMI programming examples that illustrate how to design

intuitive, efficient, and responsive interfaces for industrial control systems.

Understanding how to program Delta HMIs not only enhances operational efficiency but

also improves the interaction between operators and machinery. By integrating these

examples with relevant programming techniques, you can create dynamic screens,

alarms, data logging features, and communication protocols tailored to your specific

automation needs.

Getting Started with Delta HMI Programming

Before diving into examples, it’s essential to grasp the basics of Delta HMI programming.

Delta Electronics provides a user-friendly software called DOPSoft, designed specifically

for creating and managing HMI projects. This software supports a range of Delta HMI

models, including the DOP-B, DOP-W, and DOP-A series.

Key Features of Delta HMI Programming Environment

**Drag-and-Drop Interface:** Easily add buttons, sliders, indicators, and other

controls.

**Tag Management:** Link HMI elements to PLC variables or internal registers.

**Communication Protocols:** Support for Modbus RTU, Modbus TCP/IP, and Delta’s

proprietary protocols.

**Alarm and Event Handling:** Configure alerts for abnormal conditions.

**Recipe Management:** Store and recall parameter sets for different production

runs.

**Data Logging:** Record process data for analysis and reporting.

Understanding these features will help you appreciate the context of the examples shared

below.

Delta HMI Programming Examples to Illustrate Core Concepts

1. Basic Button Control and Tag Linking

One of the simplest yet foundational examples involves creating a start/stop control for a

motor. In this case, you program two buttons on the HMI—“Start” and “Stop”—that toggle

a bit in the PLC controlling the motor.

**How it works:**

Assign a boolean tag linked to the PLC’s motor control bit.

Configure the “Start” button to write a value of 1 (true) to the tag.

Configure the “Stop” button to write a value of 0 (false).

Add an indicator lamp on the HMI that lights up when the motor is running (tag = 1).

This example highlights how HMI elements interact directly with PLC data, enabling real-

time control from the operator panel.

2. Dynamic Data Display Using Numeric and Analog Tags

Displaying real-time sensor values or process variables is crucial in most automation

systems. For instance, showing a temperature reading from a sensor connected to the PLC

on the HMI screen.

**Programming tips:**

Create a numeric display widget.

Link it to an analog tag that receives sensor data from the PLC.

Set the display format to show the desired number of decimal places.

Use color changes to indicate safe or warning ranges (e.g., green for normal, red for

high temperature).

This approach improves operator awareness and helps in quick decision-making.

3. Implementing Alarm and Event Notifications

Alarms are critical for highlighting abnormal conditions. Delta HMI programming allows

you to configure alarms that trigger visual and audible notifications when certain

thresholds are exceeded.

**Example setup:**

Define alarm tags linked to PLC bits or compare analog values against preset limits.

Configure alarm messages with clear descriptions.

Set alarm behaviors such as latching (remain active until acknowledged) or auto-

reset.

Add alarm summary screens where operators can view active and historical alarms.

Incorporating alarms into your HMI enhances safety and reduces downtime by ensuring

timely responses.

4. Recipe Management for Process Parameter Control

For industries with varying product batches or recipes, managing sets of parameters via

the HMI is a huge time-saver.

**How to program recipe management:**

Create multiple data tables or arrays to store recipe parameters.

Use buttons to navigate, load, save, and edit recipes.

Link recipe parameters to PLC registers to automatically adjust machine settings.

Implement user access control to prevent unauthorized changes.

This example showcases how Delta HMI programming can streamline complex production

workflows.

5. Communication with Multiple PLCs

In larger systems, a single HMI may need to interact with multiple PLCs, possibly from

different manufacturers.

**Key points:**

Configure multiple communication ports within DOPSoft.

Assign separate tag groups for each PLC.

Use the Modbus TCP/IP or Modbus RTU protocol to establish connections.

Handle communication errors gracefully by showing status indicators.

This example highlights the flexibility of Delta HMIs in multi-controller environments.

6. Trend Graphs for Process Monitoring

Displaying historical data trends directly on the HMI allows operators to visualize process

behavior over time.

**Programming approach:**

Enable data logging for key analog tags (e.g., temperature, pressure).

Create trend graph widgets and link them to the logged data.

Configure time scales and update intervals.

Allow zooming or scrolling for detailed analysis.

Trend visualization turns raw data into actionable insights, improving process

optimization.

7. Password Protection and User Management

Security is paramount in industrial automation. Delta HMIs support user authentication to

restrict access to critical functions.

**Implementation details:**

Define multiple user levels with distinct permissions.

Protect screens or controls by requiring login.

Log user actions for auditing purposes.

Customize the login interface for ease of use.

Integrating security features ensures system integrity and compliance with industry

standards.

Tips for Effective Delta HMI Programming

While exploring delta hmi programming examples, it’s helpful to keep some best practices

in mind:

**Plan Your Screens:** Sketch interface layouts beforehand to ensure logical

navigation.

**Use Meaningful Tags:** Name your tags clearly to simplify debugging and future

modifications.

**Optimize Communication:** Minimize unnecessary data polling to reduce network

load.

**Test Iteratively:** Regularly simulate and test your project with the PLC to catch

issues early.

**Leverage Built-in Functions:** DOPSoft provides scripts and macros—use them to

automate repetitive tasks.

**Keep User Experience in Focus:** Design intuitive interfaces with clear indicators

and responsive controls.

Applying these tips enhances both the development experience and the final system

usability.
